Revision 201

Added by Kevin Woo about 14 years ago

  • Setup bootloader to initialize pins to a known safe state
  • Pulled pindefs for the toolbox out of the toolbox into common/toolbox_pindefs.h
  • Shared toolbox pindefs with the bootloader
  • Replaced all raw pin names with the #defined names
  • Optimizied out some bytes out of the bootloader by sharing variables
